3-(Trifluoromethyl)-2-picolinic Acid CAS 87407-12-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(Trifluoromethyl)-2-picolinic Acid.

CATO supplies 3-(Trifluoromethyl)-2-picolinic Acid (CAS 87407-12-3), a certified reference material (molecular formula C7H4F3NO2, MW 191.11 g/mol) for analytical method development and quality control.

Structurally, 3-(Trifluoromethyl)-2-picolinic Acid (C7H4F3NO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 191.11 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 3-(Trifluoromethyl)-2-picolinic Acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
